Interpretation

"ADt" means an air dry tonne of pulp product where the weight of the
pulp product is corrected to reflect the weight that the pulp product would be if the
pulp were composed of 10% water and 90% fibre;

"CBPROD" means, subject to subsection (2), the 90th
percentile of the daily production rate of bleached pulp produced from an on-site bleach
plant with the use of chlorine or chlorine compounds, or both chlorine and chlorine
compounds, expressed as ADt, determined by the use of statistical methods, and using a
period of time approved by a director for determination of the 90th percentile of the
rate of chlorine or chlorine compound bleached pulp production;

"compliance sampling method" means the technique used to collect
samples which are subsequently analyzed to determine if the effluent satisfies the
quality standards established under sections 2, 3 and 6;

"EFF" means, subject to subsection (2), the 90th
percentile of the rate of effluent, expressed as m3/day, including any
sanitary effluent combined with process effluent, discharged from a pulp or paper or
pulp and paper mill, determined by the use of statistical methods, and using a period of
time approved by a director for determination of the 90th percentile of the rate of
discharge of effluent;

"permittee" means a person who holds a permit issued under section 14
of the Act;

"phase I" means a compliance sampling period commencing on the date
this regulation comes into force and expiring on the date that phase II
commences;

"phase II" means a compliance sampling period commencing on a date
specified in writing by the director;

"PROD" means, subject to subsection (2), the 90th
percentile of the daily production rate of a pulp or paper or pulp and paper mill,
expressed as ADt, determined by the use of statistical methods, and using a period of
time approved by a director for determination of the 90th percentile of the rate of
production;

"96 h LC50 toxicity" means the calculated concentration of effluent
that is lethal to 50% of the test fish (rainbow trout (Oncorhynchus mykiss)) during a 96
hour exposure.

(2) If there is an insufficient number of days of production to perform a valid 90th
percentile calculation of CBPROD, EFF or PROD, the director may use the mill's chlorine or
chlorine compound bleached pulp production design figure, effluent flow design figure or
production design figure respectively as values for CBPROD, EFF or PROD until such time as
these parameters may be calculated in accordance with subsection (1).

Prohibitions

2(1) A permittee that operates a bleached kraft pulp mill that uses chlorine or
chlorine compounds to bleach the pulp shall not discharge effluent into the environment if
the amount of AOX in the effluent exceeds the lesser of

(a) a monthly average of 0.6 kg of AOX/ADt of pulp produced in the bleach plant,
or

(b) the maximum AOX discharge rate, expressed in kg/ADt, authorized by a permit
issued under section 14 of the Act.

(1.1) A permittee that operates a bleached sulphite pulp mill or pulp and paper mill
that uses chlorine or chlorine compounds to bleach the pulp shall not discharge effluent
into the environment if the amount of AOX in the effluent exceeds the lesser of

(a) a monthly average of 1.0 kg of AOX/ADt of pulp produced in the bleach plant,
or

(b) the maximum AOX discharge rate, expressed in kg/ADt, authorized by a permit
issued under section 14 of the Act.

(2) Repealed. [B.C. Reg. 321/2004, s. 25 (f).]

(3) No permittee shall discharge effluent into the environment from an operation that
produces pulp or paper unless the quality of the effluent is equal to or better than the
quality requirement specified in Column 3 of Schedule 2.

(4)
Subsection
(3) does not apply to the pulp and paper mill operations at Port Alberni
existing on July 6, 2004 or to the pulp mill operation at Port Alice existing on July 6,
2004.

(5) The pulp and paper mill operations at Port Alberni existing on July 6, 2004 shall
not discharge effluent into the environment from those operations unless the quality of
the effluent is equal to or better than the quality requirement in Column 4 of Schedule
2.

(6) The pulp mill operation at Port Alice existing on July 6, 2004 shall not discharge
effluent into the environment from that operation unless the quality of the effluent is
equal to or better than the quality requirement in Column 5 of Schedule
2.

Sampling methods for compliance determination

3(1) The compliance sampling method used to determine the effluent flow rate and
temperature shall be as specified in writing by a director.

(2) The compliance sampling method used to provide an effluent sample for
determination of the 96 h LC50 toxicity shall consist of a grab sample.

(3) The compliance sampling method used to provide effluent samples for determination
of the 5 day biochemical oxygen demand (BOD5), the total suspended solids
(TSS) and the AOX during phase I shall consist of collecting an effluent sample during a
period of 24 hours by taking

(a) a continuous sample of the effluent being discharged from each effluent
outfall,

(b) a composite of equal samples from each effluent outfall at least every 15
minutes, or

(c) a composite of samples from each effluent outfall at least every 15 minutes in
an amount proportionate to the amount of the effluent.

(4) The compliance sampling method used to provide effluent samples for determination
of BOD5, TSS and AOX during phase II shall be as specified in writing by
the director.

Sampling and reporting schedule

5(1) In accordance with section 3, each permittee that produces pulp or paper
shall sample each effluent outfall at the following minimum frequencies:

(a) 5 times per week for TSS;

(b) 3 times per week for BOD5;

(c) for a pulp mill that bleaches pulp with chlorine or a chlorine compound, once a
week for AOX;

(d) once per month for toxicity;

(e) continuous or daily grab for temperature;

(f) daily for flow.

(2) and (3) Repealed. [B.C. Reg. 321/2004, s. 25 (g).]

(4) A director may specify an alternate sampling schedule for non-process effluent
outfalls to replace the requirements outlined in subsection (1).

(5) Each permittee must submit to a director monitoring data collected under subsection (1)
or (4)
within 30 days of the end of the month in which the data is collected.
